摘要： Servo patterns for patterned media. The servo pattern includes specification of cylinder/track ID with and without a Gray code. The servo pattern space is minimized by the optimum usage of the islands. This is achieved by island allocation rules to take advantage of non-magnetic island. The island allocation also provides for easier lift-off. Logic is used to encode and decode the Gray code. Further, the Gray code is designed to stabilize the magnetic island/non-magnetic island ratio to allow for easier manufacture.

摘要： A dual speed hard drive system with an actuator retract system capable of retracting the actuator at approximately the same speed and power in both speed modes. In one embodiment, the control of resistance is used to control the amount of back-emf current supplied to the voice coil motor. In another embodiment, the circuit selectively restrict which spindle motor winding is allowed to supply back-emf current to the voice coil motor. In yet another embodiment, a voltage or a current regulator is used to control the current flowing into the voice coil motor. In all three embodiments, the amount of back-emf current supplied to the voice coil motor is proportional to the power and speed at which the actuator is being retracted.

摘要： A structure for preventing Electrostatic Discharge (ESD) damage to a magnetoresistive sensor during manufacture. The structure includes a switching element that can be switched off during testing of the sensor and then switched back on to provide ESD shunting to the sensor. The switch can be a thermally activated mechanical relay built onto the slider. The switch could also be a programmable resistor that includes a solid electrolyte sandwiched between first and second electrodes. One of the electrodes functions as an anode. When voltage is applied in a first direction an ion bridge forms across through the electrolyte across electrodes making the resistor conductive. When a voltage is applied in a second direction, the ion bridge recedes and the programmable resistor becomes essentially non-conductive.

摘要： A system, method, and apparatus for forming a high quality master pattern for patterned media, including features to support servo patterns, is disclosed. Block copolymer self-assembly is used to facilitate the formation of a track pattern with narrower tracks. E-beam lithography forms a chemical contrast pattern of concentric rings, where the spacing of the rings is equal to an integral multiple of the target track pitch. The rings include regions within each servo sector header where the rings are offset radially by a fraction of a track pitch. Self-assembly is performed to form a new ring pattern at the target track pitch on top of the chemical contrast pattern, including the radial offsets in the servo sector headers. When this pattern is transferred to disks via nanoimprinting and etching, it creates tracks separated by nonmagnetic grooves, with the grooves and tracks including the radial offset regions.

摘要： A data storage cartridge having an data storage device, such as an encased magnetic disk drive assembly, is, in one embodiment, of generally an exterior dimensional form factor of a tape cartridge having a leader block with a hole therethrough for engagement by a threading pin. To distinguish the cartridge from a tape cartridge, the cartridge shell comprises a blocking portion at the location of the leader block hole. A transfer station both identifies the cartridge and indicates the presence of the cartridge at an end of travel in a cartridge receiver, employing an optical source and an opposed sensor directed toward the leader block hole when a cartridge is at the end of travel. In another embodiment, an encased magnetic disk drive assembly is supported and mounted in a cartridge shell by a shock mount. A flex cable interconnects the rear of the encased magnetic disk drive assembly with an external data transfer interface at the opposite side of the cartridge for data transfer with respect to a transfer station and to provide mechanical isolation.

摘要： A shock mount structure facilitates shock absorption for a device. An outrigger, preferably two wing-like outriggers at diametrically opposite sides of the device, is mounted to the device at an attachment point, and is positioned between two contacting force absorbing members, distributing the shock force to the force absorption members, and supporting the device against slippage with respect to the force absorption members. Leaf spring tabs are formed within the cartridge shell, spaced from an edge of the cartridge shell to allow their flexure. The force absorption members are positioned between the device and the leaf spring tabs, contacting the tabs, such that the tabs assist in absorbing shock force directed at the leaf spring tabs.
